You might take a look at the Census Bureau's Z5CTA files, I believe they include the congressional district.

Only the United States and the Philippines have ZIPCodes Â® . Other countries have various systems of postalcodes, but the name "ZIP Code" applies only to the postal codesus…ed by the United States and the Philippines.

In particular, US Zip Codes are 5digits, with an optional 4-digit extension (e.g., 12345-1234),while Philippines Zip Codes are 4 digits (e.g., 1234).
